Someone on this board posted an ongoing story called Sorry, You're on Your Own.
It was based on what he called "the crunch" (I think). It was set in a rural area that had been pretty much abandoned to its own after an increasing governmental crisis that culminated in utilities going down. The main characters were left to fend for themselves as they had very little idea what was going on in the outside world and several parties had begun to look after themselves at the expense of others. Basically it was like the TV show Jericho but without the nuclear blasts.
He continued to adapt the story as he went on based on feedback from the board and the story seemed to expand organically, but I don't remember if he ever finished it. It was pretty good though.
